Title: The Discussion on Improving the Indium Smelting Process and Enhancing the Quality of Crude Indium
Abstract: This paper has introduced sevral processes in the process of producing indium:Zn,Cd,Fe are removed through neutral leaching from enrichment slag;Bi,Cu,Pb,Sn,As and Sb in the feed are removed by putting iron powder into feed;Bi,Sn in the stripping solution are removed by the hydrolysis precipitation and adding indium tablets to replace them;Cd in the crude indium is removed by vacuum distillation.These processes reduce the impurities in crude indium and improve the quality of the crude indium.
